Correct Answer: C. E-waste
E-waste includes discarded computers, mobile phones, and household appliances. These items often contain toxic substances like lead and cadmium along with valuable metals like gold. Improper handling of e-waste poses severe health risks to informal sector workers.
Which waste treatment process uses high temperatures to convert waste into ash and heat?
Correct Answer: D. Incineration
Incineration is a waste-to-energy technology that significantly reduces the volume of solid waste. It is particularly useful for medical waste that requires sterilization. However, it requires advanced filters to prevent toxic gases from entering the atmosphere.
Which of the following is considered 'Green Waste'?
Correct Answer: C. Hedge trimmings
The correct answer is 'Hedge trimmings'. Green waste refers to organic garden or park waste that is rich in nitrogen. It can be easily composted to return nutrients to the soil. Proper collection of green waste prevents it from rotting in landfills and producing methane.
What is the primary benefit of 'Source Segregation' of waste?
Correct Answer: A. Lowers the cost of recycling
The correct answer is 'Lowers the cost of recycling'. Sorting waste at home prevents recyclables from being contaminated by wet organic matter. Contaminated paper or plastic is often impossible to recycle and ends up being wasted. This practice is the foundation of any successful municipal waste system.
Which organization provides the guidelines for 'Biomedical Waste Management' in India?
Correct Answer: D. Central Pollution Control Board
The CPCB formulates rules and monitors the implementation of waste standards across India. These guidelines ensure that hospitals handle infectious waste without harming the public. State boards work under the CPCB to enforce these environmental laws.
What is 'Upcycling' in waste management?
Correct Answer: A. Creating higher value products from waste
Upcycling transforms waste materials into something of better quality or environmental value. For example, using old tires to make furniture is a form of upcycling. It differs from downcycling, where the material quality decreases over time.
Which hazardous material is commonly found in old thermometers?
Correct Answer: D. Mercury
Mercury is a liquid metal used in traditional thermometers due to its thermal expansion properties. It is highly neurotoxic if the thermometer breaks and the liquid is handled or inhaled. Modern medical practices have shifted to digital thermometers to eliminate this risk.
What is the 'Great Pacific Garbage Patch' primarily made of?
Correct Answer: A. Microplastics
This patch is a massive collection of marine debris, mostly small plastic particles that do not biodegrade. It is located in the North Pacific Ocean and is trapped by circular ocean currents. These microplastics enter the food chain, harming marine life and humans.
Which color bin is used for disposing of 'Red' category biomedical waste like syringes and catheters?
Correct Answer: D. Red
Red bins are used for recyclable contaminated waste such as plastic bottles and tubes. This waste is sterilized using an autoclave or microwave before being sent for recycling. It ensures that plastic used in healthcare does not spread infections.
